uts in one dozen. You determine that it costs $0.32 to make each donut. Each box costs $0.18 per square foot of cardboard. There are 144 square inches in 1 square foot.

A box of donuts would cost: b = 3.84 + 0.18f

First, we have to find the total cost of the donuts. 
12 x 0.32 = 3.84

Next, we need to determine the cost of the box. However, we don't know the surface area, just the cost per foot. We can multiply the number of square feet of the box by $0.18 to find the cost.

So our equation could be:  b = 3.84 + 0.18f (where f is the surface area of the box in square feet)

What is the measure of DA? 15 90 105 165
seraphim [82]

Answer:

D. 165

Step-by-step explanation:

if A+n=180

75+90+n=180

165+n=180

n=180-165

n=15

A+n=180

A+15=180

A=180-15

A=165 (D)

A cheetah can run at its top speed for about 25 seconds. Complete the table to represent a cheetah running at a constant speed.
AleksandrR [38]
X = 650 + 60t

The cheetah must arrive at the same place at the same time:

x = 90t

650 + 60t = 90t

30t = 650

t = 650/30 ≅ 21.7 s

It takes the cheetah a little more than 20 s running at 90 ft/s to reach the moving antelope, so assuming the antelope can maintain its speed of 60, it is safe.

Francine has a piece of wood that is five 5 5/12 feet long she uses three 3 1/4 feet of the wood from a science project how much
zhannawk [14.2K]

Answer:

4/3 ft

Corrected question;

Francine has a piece of wood that is five 5/12 feet long she uses three 1/4 feet of the wood from a science project how much for just Francine have left.

Step-by-step explanation:

Given;

Francine has a piece of wood that is five 5/12 feet long.

Total amount of wood T = 5 × 5/12 ft = 25/12 ft

she uses three 1/4 feet of the wood from a science project.

Amount of wood Used U = 3 × 1/4 = 3/4 ft

The amount of wood left equals the total amount of wood minus the amount of wood used;

The amount of wood left L = T - U = 25/12 - 3/4

L = 25/12 - 9/12

L = 16/12

L = 4/3 ft
